ABSTRACT:
The Mullineux map is a function on partitions which arises in the representation theory of the symmetric group. The Mullineux problem is to describe this function purely combinatorially. I will describe the background and the history of this problem and explain the known combinatorial solutions, and then talk about a new solution based on crystals and regularisation.
